- We will move through this chapter very quickly (done Friday), so it's extremely important that you do your homework with max effort!
- Skip conditions for #5 (Do the conditions for 3/7)
*If you get stuck check out the step-by-step example on page 498-500!
2.) Be sure to sign up for our MANDATORY SATURDAY SESSION on APRIL 1st! The sign up sheet is in the back of the classroom!
- We're using this time as another class, so we'll be learning new stuff! Be there!
- You can also sign up for April 22nd, but you don't have to yet...
- Remember, the April vacation session is not mandatory...we'll talk more about that as we get closer...
- You will have a take home test over April break; the review session will be an opportunity to come in and work on your take home test in groups and ask me any questions you might have!
3.) Last chance for extra credit! If you didn't see last night's blog post you have one more night to do some extra credit....
- Write the statements below on a separate piece of paper (for me to collect) -- you MUST write each statement to receive any extra credit!
- Determine if the statement is true or false
- If the statement is false, explain why OR change the statement to make it correct!
- Here are the 5 statements:
1. A sample of 100 fuses from a very large shipment is found to have 10 that are defective. The 95% confidence interval would indicate that, for this shipment, the proportion of defective fuses is between 0 and 0.28.
2. A point estimate consists of a single sample statistic that is used to estimate the true population parameter.
3. A population parameter is used to estimate a confidence interval.
4. Holding the sample size fixed, increasing the level of confidence in a confidence interval will lead to a wider confidence interval.
5. The width of a confidence interval equals twice the margin of error.
